SPECIFICATION formi g part of Letters Patent No. 256,794, datedtfiApril18, 1882 Application filed October 4, 1ss0.' (No mode1.)

' To all whom 'it may concern:

.Be it known that we, MAURICE GONVERSE and FRANK ROADY, of Cleveland, inthe county of, Guyahoga and State of Ohio, have invented certain new anduseful Improvements in Machines for Making Barbed Fence-VVire; and we dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the [0 art towhich it pertains to makeand use it, reference being had to theaccompanyingdrawings, which form part of this specification.

Our invention relates to machinery for barbingfencc-wires; and itconsists in the features and combinations hereinafter specified andclaimed.

.In the drawings, Figure 1 represents our device in side elevation.Figs. 2, 3, 4, and 5 are detached and detail views, illustrating thebarb 2o bending and applying mechanism in the various stages of itsoperation. Fig. 6 is a view showing the pinching-fingers and theirassociated parts, logetherwith the stationary cutter.

.A is a frame or table of any suitable construction, dimensions, andmaterial for carrying and accommodating the various partszof ourmachine. 7

B is the main shaft, to which driving-power 0 is applied in any suitableway. Upon themain shaft B are placed four cams, one cam, O, suitablyconstructed to impart a reciprocating motion to the bent lever O, whichis pivoted to the frame A. One arm of this lever 5 C engages with thecam O, and the other is connected by a link, 0 with a lever, 0 which isalso pivoted to the frame A, as indicated.

' Upon the link 0 is carried the anti-friction guide-pulley C Thefunction of the appara- 4o tus as thus far specified is to take up theslack of the wire as it is delivered from the barbing and feedingmechanism, and in the interval when the delivery of barbed wire from thesaid mechanism hasceased to give up the slack to 5 the spooling andtwisting mechanism.

Heretofore when a spooling apparatus has been used with barbingmechanism in which the main or strand wires are fed intermittently thespoolhas been obliged to conform itself to the intermittent feed,revolving rapidly while" the barbed wirejs delivercd from the barbingmechanism and; stopping when the delivery ceases. To etfecttheintermittent spoolin g the spool has been revolved through springs orfriction-bearin gs, whereby it is allowed to come stopping obviouslystrains and produces wear in the machine, and obviously, also, it is notconducive to the regular and uniform winding of the barbed wire on thespool.

3 By means of the automatic take-upbefore referred to, the spool-in gapparatus is rendered independent of the intermittent delivery of thewire from the barbing mechanism, the take-up controlling the slack, sothat the spoolin g apparatus is supplied continuously and uniformly. Asshown, the cam O is so shaped that the slack is rapidly taken up duringthe jfeed, (corresponding to the quick movement ;imparted to thefeed-wheel F, as hereinafter explained,)' and is given up more slowlyduring the barbing= operation when the wire is -stationary, the inclinew operating the levers G G to take up the slack, and the incline w,which is less oblique to the plane of rotation of theeam, returningthem. is led in the manner shown in thedrawings over apulley, G at thefree end of the lever 0 thence under the pulley 0%, out to the spoolingandstrand-twisting mechanism.

The next cam, D, upon the main shaft is designed to actuate thebarb-wire-feeding mechanism, and this cam is constructed to impart tosaid barb-wire-feedin g mechanism a prompt feeding motion and a returnmotion, which may be either slow or fast, as desired.

Themechanism actuated by the cam D may be described as follows:

D is a bent lever, pivoted at its angle to the frame A. One arm of thislever engages with the actuating-cam D, and has imparted to it areciprocating horizontal motion, which is converted into a reciprocatingvertical motion at the opposite arm of said lever. To this oppo- Thebarbed wire v site aim is attached. a link, Dflwhich passes up andconnects with a one-way clutch device, D The clutch 1) may beconstructed in any of the many well-known ways, so that the barbwire Lwill be grasped and fed down with each downward movemcntof said clutch Dbut will. be permitted to slip through said clutch on its upwardmovement.

To enable barb-blanks of different lengths to be fed and sever d,adjusting-holes D in the levtr D are provided.

By coupling the link D into the adjustinghole nearest the pivotal pointof the lever D the'elutch mechanism D will be given its shortest feedingmotion, whereas if the link D is pivoted to the extremity of the arm ofthe lever D the clutch and barb-wire-fceding mech anism will be givenits maximum feeding movement and the barb will be fed and severed. Thecam- D is to be adjusted upon the main shaft B in such a manner as toimpart to the barb-wire-feediug mechanism its motion and operation inproper concert with the other parts of the machine in the manner and tothe efl'eet hereinafter described. 7

' The next cam, E, is for imparting alrintermittentreciprocating motionto the pinchingfingers that hold the strand-wires in position while thebarb is being fed and applied. This mechanism consists of a lever, E,ofthe third order, pivoted to one end to the frame A, e11- gaging at itsmiddle portion with the cam E, and'jointed at its upper end to a link, Ethus connecting the lever E" with a head-block, E This headblock moveshorizontally upon suitable fixed guides, E and carries thepinchingfingers E The arms of these fingers are associated with one ormore springs, E, that exert acontinuous pressure tending to open saidfingers. The arms ot'the fingers E from the point pr their intersectionand pivotal attachmentto'the head-block E have their outside surfacesdiverging rearward. These fingerarmsmove between stationary pins or lugsE which operate, as the head-block E moves forward, to bring togetherthe finger-arms, and thus clutch thestrand-wires in the manner and forthe purposes hereinafter to be described.

As the head-block E recedes the springs E will openit'hepinching-fingers and permit the bar-bed wireto pass through. The'cam Eis to be adjusted upon the main shaft B in such a manner as to impartmotion to the pinchingfingers in proper concert with the operations ofthe-other parts of the machine, as will hereinafter be described.

The fourth cam,F, upon the main shaft B is for imparting an intermittentrotary motion to the feed-wheel F. The connect-ion between the cam F andfeed-wheel F is more to be compared to a worm-gear than otherwise, asthe point of said cam F engages with pins or teeth F and as said cam isrevolved its impingement against the sides of said pins or teeth impartsto the feed-wheel F an intermittent rotary motion. This cam F is soconstructed and adjusted upon themain shaft B as to impart to the wheelF a feeding motion just after a barb has been applied to the strand- Gis a gear-wheel placed upon the main shaft B, which meshes with anddrives the barb severing and applying mechanism.

Before describing the specific construction and operation of the devicefor severing and applying the barbs, we shall specify the concert ofaction between the various parts of our machine.

We will suppose a barb to have just been applied to the strand-wires bythe barbing mechanism yet to be specified. When the barb is applied theclutch D through the influence of the cam D, raises to a height equal tothe length of the barb-blank, and ready upon its downward motion toclutch the barbwire and feed a blank forward to be bent upon thestrand-wires. At the same time the pinching-fingers E recede and open,and the cam F i imparts a quick feeding motion to the wheel F. Thisoperates to draw the strand-wires through the machine a length equal tothe distance between the barbs. the clutch D descends and feeds a properlength of barb-wire. pinching fingers move forward and grasp the strandwires to hold them in proper position and relation during theapplication of the barb. After the barb is applied the operation justdescribed is repeated.

Having now set forth the construction, operation, and concert of actionof the parts actuated by the cams G D E F, we will now proceed to adescription of the barb-applying mechanism and its operation.

As the main shaft B is kept in constantrotation, it will be evident thatthe barb-applying mechanism is also kept in constant and evenrevolution, and this feature of a constantly-revolving barb-applyin gapparatus is, so far as we are aware, novel with this our invention, andit constitutes a very important feature- 0f our device.

For the sake of convenience in the specification and claims hereinafterfollowing, we shall refer to the barb severing, bending, and applyingapparatus collectively as a harbinghead, and this barbing-head, with itsvarious component parts, is illustrated in Figs. 2, 3, 4., and 5 of thedrawings. It may be described as follows:

H is a stationary earn fixed upon the end of a stationary shaft, H,around which loosely revolves the gear-wheel G, driven by the wheel G.The shaft H is hollowed or channeled to admit of thepassagelongitudinally through it of the strandwires K. Thesestrand-wires emerge from the face of the barbing-head through twoapertures, K, located in the center of the face of the stationary cam H,as indicated in Figs. 2, 4, and 5 of the drawings. The

office of the cam H is to impart a hammering or pressing motion 'to thebarb-bendingfinger- At the same time the When this is accomplished 1 toobars Rfor the purpose of firmlyhending and applying thebarb I1. to thestrand-wires K.

Rigidly attached toor formed with one side of the gear-wheel G is aplate or disk, M, which of course revolves with the gear-wheel G. Uponthe face of theplate M is fixed a revolving shear-blade, N, for severingthe barbblank. Pivotally attached to this disk M are two levers, 0. Oneend of these levers impinges against and is operated by the stationarycam H, and is held against said cam by suitable springs, O. Thelevers Oare pivoted at O to the face of the disk M. To the outer end of each ofthe levers O are adj ustably attached the bending finger-bars P. Thesefinger-bars are attached to their respective levers O by the slot andset-screw connection indicated in the drawings. It will be evident thatas the disk or plate Mis revolved around the stationary cam H the levers0 will be rocked twice upon their pivots at every revolution of the diskM, and it is also evident that when the levers O are rocked or moved bythe stationary cam H it will operate to bring together in a directiontoward each other the bending finger-bars P, as indicated in Fig. 5-

of the drawings. The barb-bending fingerbars P are provided at theirinner ends with grooved or notched noses P, as indicated in Figs. 2 and3 of the drawings, and these noses are so constructed and relativelyarranged that as a barb-blank, L, (see Fig. 2,) is fed to thebarbing-head it will pass down, not only between the strand-wires K, butalso between the bending fingers and noses P P. As this is done therevolving shear-blade N and the stationary blade .L (fixed to thestandard N of the frame A) operate to sever the barb-blank in a slantingway, so as to point it. This slanting cut is effected by feeding thebarbwire to the barbing-head ataslant, asindicated in Fig. 3 of thedrawings, so that when the vertical cutting-blades N N sever thebarbblank it will be at an acute angle to the longitudinal axis of thebarb-wire. As soon as the barb-blank L has been severed the fingers andnoses P P grasp it, and pressing upon its ends at opposite sides, asindicated in Fig. 4, begin to bend said blank around the strand-wires.Meanwhile the pinching-fingers E are grasping the strand-wiresimmediately in front of the point where the barb is being applied, so asto hold said strand-wires rigid while the finger-bars are revolving andbending the barb upon them. As the disk revolves, carrying with it thebending-fingers P P, the barb is bent around the strand-wires, asindicated in Figs. 4 and .5 of the drawings, and whenever thebarbing-fingers are in a vertical position the stationary cam Hoperatesto bring them together with a bending or pressing movement, (see Fig.5,) which results in bending the barb closely and firmly upon thestrand-wires.

. After a barb has been applied as just specitied the cam F operates toactuate the feedwheel F, the pinching-fingers relax their grip andrecede, and the strand-wires are drawn forward, while the next.succeeding barb-blank,

as indicated in Figs. 2 and 3, is fed into the barbing-head to besevered and bent uponthe strand-wires in the manner already specified.
